         law or equity.

                  (c)  Return of Documents and Other Property. Upon the
                       --------------------------------------
         termination of the Employee's employment with the Company, or at any

         possession or under the control of the Employee.

                  (d)  Intellectual Property Rights. Employee acknowledges and
                       ----------------------------
         agrees that in consideration for his employment with Company and in
         exchange for the consideration to be paid to Employee in connection
         with such employment, all creative works Employee produces in
         connection with his employment by Company which relate to Company's
         actual or demonstrably anticipated research or development, including,
         without limitation, any invention, formula, pattern, compilation,
         computer program (and related documentation and source code), device,
         method, technique, drawing, process or other intellectual property or
         property right (collectively, "Intellectual Property"), shall be
         considered to have been prepared for Company as a part of and pursuant
         to Employee's employment with Company. Employee shall disclose to
         Company the existence of such Intellectual Property when he becomes
         aware of its existence, and Employee agrees that any such Intellectual
         Property shall be owned by Company regardless of whether it would
         otherwise be considered a work made for hire. Employee agrees to

<PAGE>

         execute any documents which Company deems necessary to protect
         Company's interest, including assignments, and further agrees to give
         evidence and testimony and take any other reasonable actions as may be
         necessary, to secure and enforce Company's rights.

                  Notwithstanding anything set forth in this Section 11(d) to
         the contrary, the parties acknowledge and agree that any Intellectual
         Property that Employee (i) has developed or was in the process of
         developing prior to his becoming employed by the Company or which he
         develops during the Term, and (ii) has not used any of Company's
         resources (whether materials, equipment, supplies, or other employees,
         contractors or consultants of Company) in connection with such
         development, shall be owned by Employee (the "Employee Intellectual
         Property"); provided, however, Employee shall promptly notify (the
         "Development Notice") Company of the existence of such Employee
         Intellectual Property. The Development Notice shall completely describe
         the Employee Intellectual Property and the applications for such
         Employee Intellectual Property. If within 30 days after Company's
         receipt of the Development Notice Company notifies Employee that
         Company would like to purchase or license the item of Employee
         Intellectual Property which is the subject of the Development Notice,
         then Company and Employee shall negotiate in good faith for the
         purchase or license of such item of Employee Intellectual Property.
         Employee agrees that he will not directly or indirectly disclose the
         existence of the Employee Intellectual Property to any third party
         unless Company either notifies Employee in writing that Company does
         not elect to purchase or license the Employee Intellectual Property or
         Company fails to notify Employee of its intent with regard to the
         purchase or license of the Employee Intellectual Property within 30
         days after the date of Company's receipt of the Development Notice.

subject to the terms, qualifications, restrictions, limitations and conditions
of the Company's benefit programs, as amended from time to time, and benefits

In order for Employee to be eligible for certain Company benefits Employee may
be required to make the contributions required by such benefit plans. The
benefits described on this Exhibit A will be offered to Employee and
administered by the Company in a manner consistent with other employees of the

         5.       Ability to participate in the Company's 401(k) Plan and
                  receive Company's matching contributions, if and when made1.
         6.       Company will pay up to $1,000 per month to reimburse Employee

                  Florida area for Employee's use during the Term.
         7.       In accordance with the Company's policies adopted from time to
                  time, the Company agrees to reimburse the Employee for the
                  Employee's reasonable expenses incurred in connection with
                  moving the Employee's household goods currently located in the
                  Orlando, Florida area to a metropolitan area to be determined;
                  provided that the Employee submits to the Company at least
                  three competitive bids from moving companies selected by the
                  Employee and the Company approves the bid utilized for such

                  the Company's policies regarding the same.

-----------------------
1        The Company's 401(k) plan does not require the Company to match
         employee contributions. It has been the Company's past practice to
         match 25% of employee contributions but there can be no assurance
         the Company will continue that practice in the future.
